For reenterable models of IP networks with dynamic routing according to RIP protocol, measuring subnets for QoS parameters evaluation have been essentially modified and extended. Online algorithms of statistical analysis have been specified by colored Petri nets. The mean and variance of the packet delivery time have been evaluated. As a result, the computation precision has grown and an essential...
IPv6 is an ultimate solution to the Internet address exhaustion. It is believed, the protocol will be requested by not only human but also everything on the earth surface. Furthermore, the improvement on the protocol is important to achieve IP packets transmission efficiently. Processing technology has been improved to become very fast packet processing both in host as well as intermediate systems...
Existing NAT solves to IP address exhaustion problem binding private IP address and public IP address, and NAT traversal such as hole punching scheme enables to communicate End-to-End devices located in different private networks. However, such technologies are centralized the workload at NAT gateway and increase transmission delay caused by packet modification per packet. In this paper, we propose...
Mobile Internet access has become the norm rather than an exception in our daily lives, resulting in a large proportion of traffic attributed to mobile devices. To enhance the mobility support in Internet architecture, many research initiatives have devoted to investigating Named Data Networking (NDN) as the fundamental paradigm for the future Internet. NDN supports the consumer mobility by re-issuing...
Wi-Fi hotspots deployed by domestic networks are an attractive approach to foster ubiquitous Internet access for mobile computers. However, it raises several security issues, since the owners of such hotspots cannot be trusted to be honest; therefore, visitors should consider them as potential Man-in-the-Middle attackers. On the other hand, the owners of such hotspots should not be legally accounted...
The transmission of the Voice over Internet protocol requires high quality of speech to update this service. VoIP signal quality can be degraded by network layer problems which includes delay, packet loss and jitter. But the frame loss while transmitting voice over internet services may generate audible distortion in the perceived speech quality. The simulation model of VoIP network under impairments...
